The majority of previous attempts to increase stress resistance in grapevine employed non-grape genes or promoters. However,in ongoing research, a number of grapevine-derived genetic elements, including several pathogens is related genes were isolated from disease resistant, sexually-compatible V. vinifera hybrids and plants over expressing these genes were placed under field conditions [1,119]. These plants contain genes encoding the PR1 variants[119], VvTL1 (PR5) [35], VvAlb1 [52], homologues of VvAMP1 and VvAMP2/defens in [120] and an orthologue of Snakin-1
